To (LZZ ml 1 0177. 77; party concern.-

Be it known that 1, Armor AUeUsTUs Low, a citizen of the United States, residing at Horseshoe, St. Lawrence county, and State of New York, have invented certain new and useful Improvements in Hydrocarbon-Motors, of which the following is a specification, sufficient to enable others skilled in the art to which. the invention a )pertains to make and use the same.

This invention relates to marine motors which are actuated by the explosion of vaporized hydrocarbon and is designed to effect the practically-noiseless discharge of the resultant gases and other products of combustion.

The invention consists in the novel con struction, combination, and arrangement o'l. parts, all as more fully hereinafter described, shown in the drawing, and. then particularly pointed out in the appended claims.

The accompanying drawing illustrates the construction embodying the invention and, with the characters of reference thereon, forms a part of this specification.

B represents the hull o'l. a boat or marine vessel of any kind submerged below the water-line w w.

E is a gas, kerosene, or other hydrocarbon. engine oil any description, the operative parts and connections being omitted in the drawing, with the exception of the power-shaft a. and the discharge-coeduit l). The dischargeconduit D is provided with a rel let-valve or damper d, which may be opened. in Whole or in part while the engine is started or to regulate or modify the tension within. the said discharge-conduit, if desired. The lower portion cl oi the dischargeconduit D is situated in the conical water-channel C, extending across the hull of the vessel and opening under the water-line on both sides thereof so as to provide for a free current of water through said conical channel 0, and this current is augmented and insured by the discharge of the products of combustion from the end of the pipe (1, which latter is provided with a check-valve d to prevent back pressure and to exclude the water from the dischargeconduit. By this means a continuous supply oi :lresh cold water is brought into contact with the discharge-pipe d.

The suction created in the discharge-conduit is augmented by the condensation oi the products o'l combustion by the fresh cold wa ter in the jacket C, the partial vacuum thus created reducing the resistance to the minimum and adding to the effective power of the motor. This decrease in resistance is such. that the diameter of the discharge-pipe D may be :lnaterially reduced, as indicated in the drawing, with beneficial results.

The water-channel G is inclined slightly with relation thereto, as shown in the drawing, so that the discharge-port c lower than the upper portion of the top oil the inlet 0, the dischargepipe of course being arranged to eject the products o'l." combustion toward said discharge-port c. I also provide the wider end 0 of the channel, which constitutes the mouth or inlet-port thereof, with a screen .9 for the purpose of excluding solid matter. The water-chann cl C is made in the form. of a truncated cone, the longitudinal axis ol. which is inclined downwardly from the horizontal, so that the smaller or truncatcd discharge end of the said conical waterchannel farther below the water-line than the top oil" the inlet. By this means the convergent walls ol" the said channel not only guide and concentrate the low of fresh cold water around. the discharge end of the chan nel or conduit, but by having the dischargeconduit located in said channel and discharg ing at the smaller end of the same near its discharge into the surrounding water all tendency or liability of backllow within the said conical water-channel is counteracted.

hat I claim. as my invention, and desire to secure by Letters Patent, is

1. In a motor-drivei1. vessel, the combination with an internal-comlmstion motor for driving the same, of a water-channel in the shape oi" a truncated cone extending across the hull of the vessel below the water-line, and an exlmust-pipe from the :inotor located in said channel and discharging at the smaller end of the same near its delivery into the surrounding water for the purpose of counteracting backflow Within said conical Waterchannel.

2. In a 1notor-driven vessel, the combination with an internal-combustion engine for driving the same, of a Water-channel in the shape of a truncated cone extending across the hull of the vessel beloW the Water-line, and an exhaust-conduit for the products of coinbustion, a relief-valve in said conduit outside the said channel, and a check-valve in said conduit Within said channel, said exhaust conduit extending within the water-channel axially thereof and terminating Within the same in proximity to the delivery end of said channel into the surrounding Water for the purpose of counteracting backflow within said conical Water-channel.
